Taking Sonic Boom for a Spin on Wii U and 3DS - NintendoLife

NintendoLife: "Back in May 2013 Nintendo announced that it had entered into a partnership with Sega to bring a series of three Sonic games exclusively to its systems. Sonic Lost World and Mario & Sonic at the Sochi 2014 Olympic Winter Games were the first products of that arrangement, and the upcoming Sonic Boom games — one on Wii U and one on 3DS — are set to round out the trio. Sega has an ambitious multimodal strategy for Sonic Boom, including a TV series on Cartoon Network, a line of TOMY toys and, of course, the two separate Nintendo-exclusive games: Sonic Boom: Rise of Lyric for the Wii U, and Sonic Boom: Shattered Crystal for the 3DS."

So the wii u version plays like the Adventure series, but with better combat, and the 3ds version plays like more traditional Sonic games, but with multiple characters to switch to, at any time, to access optional paths. Sounds fun!
